Right now this leads to some inflation of RSS cause previously 
used and now freed pages can only be reused when the whole pool 
(e.g. 4MB or 16MB) is free again.
It doesn't seem sensible to reserve 16MB only for big (>PAGESIZE) 
allocations. In particular once the pages are dirty and mapped, 
you'd rather want to make use of them.
